The 5 Hydraulic Cylinder Resealing Must-Knows

Your hydraulic cylinder resealing process has already begun. You’ve disassembled it and you have a bag (or box) of brand-new seals. Now you want to get the new seals in and the hydraulic cylinder assembled and back on the machine. But you want to do it right the first time. And this is good. Because the last thing you need is to do all this work and the hydraulic cylinder starts leaking again. Because there are a few points that you should know when doing a reseal. Well, there are five points that are important to know. By considering these, you can further improve the reliability and restore performance of your hydraulic cylinder after resealing. Also, we’ll assume the seals you’re supplied with are suitable for the machine and its hydraulic fluid. #1 Inspect Start by inspecting the hydraulic cylinder itself. Look at the condition of the bore and rod for wear, scoring, or damage. Repair or replace any damaged parts. Installing new seals won’t make up for damaged parts. #2 Quality You’re going to inspect the seals and make sure what’s supplied are the correct seals. On top of this, check the condition of each item. Seals may appear new at a glance. Look closer… Are they at a standard or condition to what you’re satisfied with?  If not, get it replaced. #3 Technique An insider secret to installation technique is to avoid forcing the seals and causing them to kink into sharp bends. If you’re finding it difficult to install a seal in an internal groove then use dedicated seal installation tooling to assist. For external seals, such as those for the piston, only expand the seal enough to slip over the component body. Over-stretching can permanently damage the seal and reduce its life. #4 O-Ring After you’ve installed an O-ring, check that it’s not sitting twisted. Having a twisted hydraulic O-ring compromises the sealing performance and life. Majority of times O-rings are installed manually, so use tools without sharp edges. #5 Lubricant There’s a huge range of lubricants and greases, but not all are compatible with your seals. Lubes that have solid additives, such as molybdenum disulphide should be avoided. It may be suitable for pins and bushes, rod ends, and CV joints, but not for hydraulic cylinder seals. A compatible and readily available medium for lube is the machine’s hydraulic oil. You can use hydraulic oil to lube the seal that need to be stretched slightly as it is being located into the groove, such as a piston seal. Lubricate the barrel bore with a film of hydraulic oil before assembly.

Top 4 Reasons Hydraulic Cylinder Rods Bend

A major failure for hydraulic cylinders is when the rod bends or buckles when in operation. Usually when a rod is bent it also damages the gland, and at times, the piston and bore too. Pretty much have the hydraulic cylinder to catastrophically fail. Why can the other parts fail? A hydraulic cylinder has specific engineered tolerances and clearances. The rod, gland, piston, and barrel bore are all ‘straight’ to each other. So when a rod has a bend in it, it’s centre axis is no longer inline or straight with the other component. This puts excessive loads to guide rings and bushes. The piston becomes ‘crooked’ and the gland gets damaged as it becomes a fulcrum for the bend. Retracting a bent rod into the cylinder does not straighten it again. The machine should be immediately stopped and the failed hydraulic cylinder repaired or replaced. So here they are… Top 4 Reasons Why Hydraulic Cylinder Rods Bend Rod diameter too small Inadequate rod material strength Improper cylinder mounting arrangement Machine misuse/abuse by the operator What You Can Do About It If there are loads greater than the rods ability to withstand bending or buckling, then a new rod should be manufactured with an increased diameter and/or higher material strength. For reason No.4, it just comes down to operator training and care for the machine or attachment. If they are being used outside the manufacturer’s original design and operational intent then don’t be surprised if the hydraulic cylinders fail and the overall machine uptime and life is drastically reduced. How to spot a possible bend in a rod Here are some way you can spot a possible bend in a hydraulic cylinder rod: ‘Juddering’ during operation An audible sound during operation Oil leakage from seals Rod scoring Irregular rod wear patten What You Need To Do If you suspect that your hydraulic cylinder has a bend or needs attention, contact us today. Getting the cylinder looked at now is far better than putting it off and having catastrophic failure. Contact us now on 07 3800 8721 and a friendly team member will help you get the best solution.

5 Steps To Remove Air Form Hydraulic Cylinders

Whenever you are installing a hydraulic cylinder to your machine, you should always assume that some air will be introduced in the hydraulic system. You can lose oil during the process of disconnecting and reconnecting hoses, fittings, burst/craning valves, or even when installing hydraulic cylinder that’s completely empty. All these situations are not a problem when you understand what dieseling is. What’s dieseling? Simply put it’s the detonation of trapped air in oil when compressed. Just think about how a diesel engine works. Dieseling can damage pistons and the seals. Shortening the life of the hydraulic cylinder. It also means it reduces machine uptime. That’s why it best practice to bleed or remove air after any hydraulic cylinder service, when getting a new cylinder, or when there’s a possibility of air that’s entered into the hydraulic cylinders, Before You Start Check the machine’s maintenance manual for the procedure that’s specific or recommended for you. The below procedure is general guideline. You need to keep the machines’ engine at a low RPM/idle throughout the whole procedure. And be patient. Don’t rush this important process. Don’t run the engine at full noise and sudden control movements to fill the hydraulic cylinder quicker. You are only promoting for dieseling to occur. The 5 Steps Keep the engine at low idle and then… Step 1: For 8 cycles, slowly extended and retracted the cylinder through approximately 3/4 of the full cylinder travel. Do this for 8 to 10 cycles. Don’t let the cylinders reach the stroke ends (bottom out), in both directions. Step 2: Pause before you change direction for a minimum of 5 seconds. Step 3: Then, slowly cycle the hydraulic cylinders to the full extend and retract travel, while keeping the hydraulic pressure low. Step 4: Pause before you change direction for a minimum of 5 seconds. Step 5: Finally, check the hydraulic oil level and top up as needed.

What You Should Know About Hydraulic Cylinder Seals

Hydraulic cylinder seals deteriorate over time due to many factors, and knowing the most common reasons behind this deterioration is vital for maintaining the performance and longevity of any hydraulic cylinder and the hydraulic system to your machine. Factors that contribute to seal deterioration include: environmental conditions, pressures, temperature exposure, and sealing materials. When a hydraulic cylinder is showing first signs of seal deterioration, such as leaks and loss of efficiency, then the best thing is to start planning to have it resealed. It is not uncommon for operators to ‘push’ the machine further and to work it longer – and even ignoring any signs altogether! Ways Hydraulic seals can deteriorate and fail 1. Extrusion: This occurs when high pressure forces the seal material to deform or extrude into gaps or clearances in the cylinder, compromising its integrity and sealing performance. 2. Compression Set: Over time, seals may lose their ability to return to their original shape after being compressed, ending up permanently deformed and loss of effectiveness. 3. Hardening and Cracking: Exposure to heat or extreme temperature, chemicals, or UV exposure can cause the seals to harden and become brittle, eventually leading to cracking or breakage. 4. Swelling: Some hydraulic fluids may cause seals to swell or expand, affecting its housing fit and sealing ability. 5. Contamination: Normal wear from repetitive motion is accelerated when contaminants, such as dust or abrasive particles, enter the hydraulic system and come into contact with the seals. When a hydraulic cylinder is showing first signs of seal deterioration, such as leaks and loss of efficiency, then the best thing is to start planning to have it resealed. Why You Shouldn’t Neglect These Signs Taking lightly any signs of hydraulic cylinder seal deterioration can have serious consequences. When seals start to deteriorate, they aren’t doing what their functions are for: sealing, guiding, wiping, and protecting. Leaking and bypassing seals leads to poor efficiency and the high risk of damage to the hydraulic system. The final result of neglect can be an expensive catastrophic failure to the hydraulic cylinder and system.   The best solution for hydraulic cylinder seal deterioration is to get it serviced. Inspect seals often for signs of leakage or damage. Seals must be replaced at the first sign of deterioration to prevent more problems. Use only high-quality seals that’s specific for the hydraulic system and following proper maintenance and operating practices, such as keeping hydraulic fluid clean and within recommended temperature and pressure limits, can help extend the life of seals.   What To Do Next For all your hydraulic cylinder enquiries and servicing call us on 07 3800 8721 and a friendly team member will help you get the the best solution.
